1. Introduction Weaning is one of the most stressful events in pig production [1]. Early weaned piglets face several nutritional and psychosocial stressors, including the transition to a solid diet and the abrupt separation of sows and piglets [2]. These events coincide with an immature immune and digestive system [3], which has consequences, such as the reduced activity of digestive enzymes, changes in intestinal morphology, and reduced nutrient digestion in the small intestine...

Fermentation products with main and side activities Feed enzymes are mostly produced by fungi or bacteria. Those living organisms produce a wide variety of different enzyme proteins. For commercial practice, only a limited number of those activities is assayed in the laboratory. Assaying e.g. the xylanase activity obviously results in a quantification of the xylanase level, while not providing information about other activities that remain present in the fermentation product. In...

The Food and Agriculture Organization of the United Nations (FAO) is increasing efforts aimed at bolstering the global response to Fall Armyworm (FAW), considered one of the top 10 devastating plant pests affecting food and agriculture.
FAO Director-General, QU Dongyu, noted today that great strides had been made by the Global Action for Fall Armyworm Control (GA), a coordination mechanism established by him a year ago, but emphasized that many challenges remain to be tackled in...

Global demand for seafood is growing at an unprecedented rate. By 2030, an additional 41 million tons of fish per year will be needed to maintain current levels of seafood consumption. Aquaculture is the solution, and soy-based feed is a sustainable and healthful alternative to traditional fish-based aquafeeds.
In particular, grouper has been identified as a desired fish in the live reef food fish trade in Southeast Asia due to their desirable taste, hardiness in captivity, efficient...

U.S. Soy has a large market in animal feed because of its rich nutritional value and its contribution to animal performance. Although alternatives exist, such as corn protein, and a growing supply of synthetic amino acids, research consistently shows that when compared to these alternatives, soy outperforms.
Dr. Hans H. Stein, a professor of Animal Science at the University of Illinois, Urbana-Champaign, conducts research in the area of intestinal physiology and feed ingredient...

Introduction Salmonellosis is a significant global public health issue and causes high morbidity rate and has a significant economic impact. Foodborne diseases persist in many countries and consider the most important public health problem. There is global improvement in food processing practices, hygiene measures, education of food handlers on the potential risks and information to consumers for proper utilization, but still so far to eliminate the foodborne pathogen problem...

Introduction Feed manufacturing equipment has been shown to be a potential source of porcine epidemic diarrhea virus (PEDV) cross contamination. Wet decontamination has been found to be the most effective method for decontaminating the surface of feed mill equipment. However, this is not practical in most current commercial feed production settings. Methods to mitigate the risk of PEDV transmission in feed and feed ingredients have been investigated, including chemical...

INTRODUCTION The increasing global population and the limiting global capture fisheries undeniably increase the demand of aquaculture. On the other hand, those will also bring about limitation to aquaculture expansion in particular of land and water utilization. Therefore, productivity enhancement in term of total production per input used becomes one of the major priority in the development of aquaculture (Avnimelech et al., 2008) . Aquaculture is the culture of...

1. INTRODUCTION Several studies have linked declining reproduction especially male fertility to toxicants found in the environment, particularly endocrine-disrupting chemicals (EDCs), such as phthalates (Wong and Cheng, 2011; Nordkap et al., 2012). One of the phthalates, Di-n-butyl phthalate (DBP) has attracted special attention due to high production volume in millions of tons annually (Swan and Elkin, 1999; Guerra et al., 2010). As a result, human and...

1. Introduction Virgin olive oil is an essential component of the traditional Mediterranean diet. Its quality is known to be influenced by a number of factors, including plant variety, environmental conditions, agronomic and harvesting practices and technological processes [1,2]. The International Olive Council (IOC) [3] and the European Union (EU) [4] have established standards that can be applied to all the olive oils subject to international trade. The Commission...

INTRODUCTION One of the important cardinals of management is feeding and it accounts for 50-70% cost of production (Peter and Bern, 2013) but there has recently been an increase in competition among the ingredients used in the manufacture of animal feed. There is consequently a great need for alternatives that can supply in the high demand for such ingredients, in particular for soya bean meal (Chisoro, 2015). The use of plants (leaf meals) that are not directly used by humans...

1. Introduction Biochar (BC) is obtained via the pyrolysis of organic material. In the process, biomass is treated by heat in very low oxygen (or other oxidizers) content, where complex chemical compounds are transformed into simpler ones, eventually yielding gaseous products such as water vapor, carbon dioxide (CO 2 ), carbon monoxide (CO), hydrogen (H 2 ), methane (CH 4 ), ethane (C 2 H 6 ), and also solid carbon residue often named...

Introduction The transition period into lactation remains one of the most challenging and important phases of the production cycle in a dairy cow. It is a transient period around calving characterised by drastic changes in the hormonal status, 2 to 5-fold (Bradford, 2020) increases in nutrient demand and apportioning of 85% of body glucose to the mammary gland. Simultaneously, the requirement for specific fatty acids escalates by more than four times (Bell, 1995; McFadden and...

INTRODUCTION Poultry population in Nigeria is put at 140 million and it is a major contributor to the economy (FMAWR, 2008). There is also a consistent rise in intensification of production and a growth rate of 306.6% between 1999 and 2004 (Glipha, 2007). The importance of these statistics is that Nigeria inadvertently contributes to environmental issues currently debated world - wide vix air and water pollution, greenhouse gas (GHG) emission, climate change etc. Owing to the...

Ingredients come to the feed processor from a variety of sources. Many of these, particularly the coarse cereal grains, require some degree of processing before they are ready to be blended into an animal ration. The process of particle size reduction improves ingredient performance during mixing and, in most cases, the nutritive value of an ingredient can be improved or more nearly realized. There are many ways to reduce the particle size of feed ingredients. Two of the most common...
